If you're using a Watts Premier reverse osmosis system, the Watts Premier RO Water Filter 50 GPD Membrane Replacement is an essential component to maintain optimal water quality. Designed specifically for models like the 4SV/4-Stage, 5SV/5-Stage, and Zero Waste systems, this membrane ensures your water is free from harmful contaminants.
One of the standout features of this membrane is its ability to reduce Total Dissolved Solids (TDS) and sodium, along with contaminants like arsenic, lead, and chromium. With a filtration capability down to 1/10,000 of a micron, it significantly enhances the purity of your drinking water.
Installation is straightforward, thanks to its compact design (1.8" in diameter and 10.75" in length) and built-in check valve. Users have reported that replacing the membrane is easy, especially if you take note of how the plastic tubes are connected before disassembly.
Durability is another strong point. The membrane typically lasts between 2 to 5 years, depending on local water conditions and usage patterns. Many users have praised its long-lasting performance, with some noting that their systems have been running smoothly for over a decade with periodic membrane replacements.
Customer reviews highlight the effectiveness of this membrane in reducing TDS levels dramatically—some users report drops from 35 PPM to as low as 2 PPM after installation. It's also compatible only with Watts Premier systems due to its unique built-in check valve design, which sets it apart from other brands.
In summary, if you're looking for a reliable and efficient replacement membrane for your Watts Premier RO system, this product delivers on all fronts—performance, ease of installation, and durability.
